Harvest is underway with 21 percent of soybeans and 10 percent of the corn crop already completed in Iowa. That's a day behind last year's progress at this time. Rain likely has something to do with it.

The U.S. Department of Agriculture's weekly crop status report released Monday indicates weather was favorable for farmers but there were reports of muddy conditions and standing water in some fields from earlier storms. Iowa Corn and soybeans are rated at 81 percent good to excellent.

It was nearly ideal for harvest in Nebraska where farmers reported 15 percent of corn harvested, behind the five-year average and 27 percent of soybeans in bins, right at average.

The USDA reports 73 percent of Nebraska corn and 78 percent of soybeans are rated good to excellent.
